3.1.3 Computer Network Topologies Network Topology is a network specification that determines the network arrangement‚ connecting the senders and receivers through lines of connection. Topologies are of both physical and logical aspect of the network. The physical topology describes the network’s physical wiring layout or shape. The logical topology describes the path through which the data moves. Both logical and physical topologies could be same or different in a same network. The physical and

TYPES OF COMPUTER NETWORKS: A computer networks is a communication system connecting two or more computers that work together to exchange information & share resources. A network may consist of microcomputers or it may integrate microcomputers or other devices with large computer. Networks can be controlled by all nodes co-ordinarily & supply all resource. These networks differ in geographical size. There are three important types of networks. 1. Local Area Network 2. Metropolitan Area

Computer Storage Devices Storage devices are used in order to store various items such as programs‚ data and instructions. Storage was used as early as 1804 by hole punching paper cards in order to control machinery. Without storage‚ the computer programs and files that exist now would not be possible. There are many different devices used for storage today such as hard drives‚ floppy drives and CD-Rom drives. Hard drives come in all computers and are the main storage device. An average hard drive

of information using different light pulse colour. Optical fibres can be used conveniently without the need for incessant repeaters as they have minimal attenuation due to the speed of light‚ which permits them to travel for long distances in the core of the fibre without touching the cladding of the fibre strand. Optical fibres due to their complex and delicate nature do not allow for information tapping and siphoning as they need to be cut to do so‚ presenting
